Be it known that I, THEODOR SoHorPE, a subject of the Emperor ofGermany, residing at Bonn. in Rhenish Prussia, Germany, have invented acertain new and useful Improvementin Ice-Chests or Refrigerators,(patented in Germany July 23, 1892, No. 67,546,) of which the followingis a specification.

In this refrigerator a series of.partitionbottomsorplatformsservingforplacing thereon the objects to becooled or to be kept ina 0001 state, are constructed hollow, and are incommunication with one another and with the elevated ice-reservoir insuch way that the ice-water from the ice-reservoir first runs into thelower hollow platform, and thence upward through the other, and finallyfrom the highest through a rising pipe which extends above the bottom ofthe ice-reservoir. The water is conducted downward from there through awaste-pipe, and may be discharged into a collector arranged, as usual,beneath. This arrangement conducts the ice-water in a serpentine routeslowly through the refrigerator in order to give to this water theopportunity of taking up the caloric, or in common language, giving offits cold, so that the same will be utilized in lowering and keeping lowthe temperature of the objects placed in the refrigerator. The providinga rising-pipe on the uppermost platform and extending it above thebottom of the ice-reservoir,has for its object to insure that theapparatus shall always hold securely filled with ice-water the hollowplatforms and their connecting tubes, and to produce a certaintransferring of the cold of the ice to the contents of the structure.

The accompanying drawings form a part of this specification andrepresent what I consider the best means of carrying out the invention.

Figure 1 is a central vertical section showing one form of my invention.In this, the refrigerator has but a single chamber and a single set ofthe hollow partitions and connections. of the construction whentheinvention is applied to a refrigerator having two or more chambers,and a corresponding number of sets of partitions and pipes. Fig. 2 is acorresponding plan view. Fig. 3 is a'plan view Fig. 2 shows in outline aportion Similar letters of reference indicate corresponding parts in allthe figures where they appear.

The ice reservoir A, wherein the ice. is placed on a grate B, isprovided with a short waste-pipe 0, having preferably a cook or cutoffdevice 0. To this waste-pipe is connected a removable waste-pipe Eleading to the lowest hollow partition bottom or platform D, andconnected by a close-fitting joint at G. The hollow platforms D, D, Dare in communication with one another by the pipes F, F, whichmaypermanently connect them. These pipes and platforms will receive thewater from the melted ice, and conduct it through. Posts I are providedfor further supporting and connecting the platform.

On the uppermost platform D there is a set-up or rising pipe K, which isof such height as to extend a little above the bottom of theice-reservoirA. This rising pipe is connected by a tight joint at H,witha waste-pipe L. At the highest point is a short air-pipe M, whichmay have a cook or cut-off device by which air may be admitted so thatthe apparatus will be prevented from working like a siphon and emptyingunintentionally the hollow spaces of the platforms. In consequence ofthe pipe E being removable from the short pipe 0, by a removable joint Wand of pipe K being removable from pipe L, the hollow platforms andtheir connecting pipes may be convenientlyintroduced and removed througha door in the side; or by removing the ice-reservoir, it may be removedthrough the top.

The pipe E through which the ice-water descends directly from the top tothe bottom is permanently attached to the several platforms, asindicated. This pipe is removable from the construction with theplatforms. The pipe L through which the ice-water descends aftertraversing the several platforms and their connecting pipes ispermanetly attached to the interior of the refrigerator. A slight degreeof independent motion of these pipes may be permitted to facilitate themaking and breaking of the joints connecting the pipe E with the pipe 0,and the pipe K with the pipe L.

Modifications may be made without departing from the principle orsacrificing the advantages of the invention. Instead of the fiatcase-shaped platforms D, D, D as shown in Fig. 1, there may be usedplatforms made of pipes or hollow metal parts having any desiredcross-sections, arranged as shown in Figs. 2 and 3, and of the form ofcross-section shown in Fig. 4, and which pipes also can be taken outbodily if desired. The entire spaces under the provision chambers andbetween them in these modifications, may be permanent parts of thestructure, the ice-water from an ice-reservoir not shown, filling thespaces between and under the chambers, and finally flowing upwardthrough the hollow platforms, and distributing its cooling influence toevery part of the several chambers. The platforms or hollow horizontalpartitions instead of being arranged horizontally may be arrangedobliquely, or even vertically. I provide before the waste-pipe O of theice-reservoir a strainer 0 in order to prevent the passage of saw-dustor other large impurities into the hollow platforms and their connectingpipes. The cross-sections of the platforms and of the pipes are madelarge in order to prevent their becoming obstructed. There may be an ysuitable drain-cock, not shown by which to empty the whole whenrequired.

I claim as my invention-- 1. In a refrigerator, the connection of thelower hollow partition bottom D with the ice reservoir A by means of awaste-pipe E, permanently connected to the said bottom, and detachablyconnected to the ice reservoir, in combination with the upper hollowpartition bottoms D, D and the connecting tubes F, F, substantially asherein specified.

2. In a refrigerator the removable series of hollow platforms as D, D, Dpipes F, F, firmly uniting such platforms, and detachable joints G andII connecting such at will with the elevated ice-reservoir A anddischarge drain pipe'L, all combined and arranged to serve as hereinspecified.

3. In a refrigerator, a series of two or more removable hollow platformsD, D, pipes F, F, uniting such platforms, and allowing the water tocirculate through the same from below, posts I, I, aiding to connect andrigidly support the platforms, pipes E, L, permanently connected, onewith the removable platforms and the other with the stationary casing ofthe refrigerator, the detachable joint W connecting the pipe E with thepipe 0 and the detachable joint I-I connecting the pipe L with theplatforms, all arranged for joint operation substantially as hereinspecifled.

In testimony whereof I have hereunto set my hand, at Cologne, Germany,this 23d day of February, 1893, in thg presence of two subscribingwitnesses.
